As of trunk revision 108659, the default next-error function in compilation-mode appears to have a run-time dependency upon subst `cl--set-nthcdr'. Recipe from `emacs -Q' (assuming current directory contains files that contain "x"): M-x grep RET x SPC * RET C-x ` Expected result: successfully go to location of first match. Actual result: go to location of first match then ding, saying: "compilation-next-error-function: Symbol's function definition is void: cl--set-nthcdr".
